Stack Exchange authentication strategy for Passport and Node.js.
npm install passport-stack-exchangePassport strategy for authenticating with Stack Exchange using the OAuth 2.0 API.
This module lets you authenticate using Stack Exchange in your Node.js applications. By plugging into Passport, Stackexchange authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
``bash`
npm install passport-stack-exchange
#### Configure Strategy
The Stack Exchange authentication strategy authenticates users using a Stack Exchange account (Stack Overflow) and OAuth tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a consumer key, consumer secret, callback URL, and API key for Stackapps. Register the application on the service page.
`javascript
var StackExchangeStrategy = require('passport-stack-exchange');
passport.use(new StackExchangeStrategy({
clientID: STACKEXCHANGE_CLIENT_ID,
clientSecret: STACKEXCHANGE_CLIENT_SECRET,
callbackURL: 'http://127.0.0.1:3000/auth/stack-exchange/callback',
stackAppsKey: STACKEXCHANGE_APPS_KEY,
site: 'stackoverflow'
},
function(accessToken, refreshToken, profile, done) {
User.findOrCreate({ stackexchangeId: profile.username }, function (err, user) {
return done(err, user);
});
}
));
`
#### Authenticate Requests
Use passport.authenticate(), specifying the 'stack-exchange' strategy, to authenticate requests.
For example, as route middleware in an Express application:
`javascript
app.get('/auth/stack-exchange',
passport.authenticate('stack-exchange'));
app.get('/auth/stack-exchange/callback',
passport.authenticate('stack-exchange', { failureRedirect: '/login' }),
function(req, res) {
// Successful authentication, redirect home.
res.redirect('/');
});
``
